93 Octane vs E85 Retune! Justin's Evo RS @ STM
 

Sunday ended up being a crappy, rainy night and ruined our plans for a cruise. But while we were all at the shop, bored, and looking for something fun to do, we happened to have a 5 gallon pail full of fresh E85 and a white Evo RS begging to drink it!

So on the dyno she went! Staying with the exact same set up as the 93 octane tune (which previously made 413 HP and 333 TQ) Emery worked his magic and pulled out 446 HP and 383 TQ, gaining 33 HP and 50 TQ... and there is definitely room to go up, but the 1050cc injectors are just maxed out at 110% duty cycle.

Maybe some bigger injectors and a double pumper might put this car a little closer to that sweet 500 stock block spot.

For those of you not familiar with this build, here is a brief mod list:

STM T3 Tubular Exhaust Manifold
PTE Non Ball Bearing 5557SP Turbo
STM Upper and Lower Aluminum Intercooler Pipes
Exedy Triple Cerametalic Clutch
STM Clutch Fork Stop
Kelford 272 Cams
Supertech Dual Springs & Retainers
Buschur Cat Back Exhaust
Buschur FMIC
STM Intake
Buschur Ported Throttle Body
AEM EMS Tuned By Emery
26 psi out of fuel, for now.

Welcome to the E85 club, Justin!

time for some bigger injectors and double pumper..

awesome gains from just switching gas to e85! 1200's going in, or bigger?

We are going to start with a double pumper. I have a feeling that will be enough to get the car to 30 psi and thats about all this turbo is gonna take.


-Em

Car feels great and smells AWESOME!.Cant thank you guys enough and to hit the track!

Trust me Im working 60 hours a week so I can get them faster. Can't wait!

-Justin

Yes....love the smell of corn fuel.

What the HP rating for the PTE 5557?

I have heard a wide range of numbers from 500-570 wheel
even on some sites. We will see how much more is left in it after we throw in the double pumper and injectors.


-Justin

Any plans to build the motor?

Track July 9th Justin. Congrats bro it didnt take much to talk you into switching that night.

Not anytime soon. I need to get other things done first. I might pull the stupid fast stock block kind of deal I hope since its not my DD. Thanks Cessna yeah it really didnt take much at all. Track is going to be some fun for sure bro.


-Justin

great power for only 26psi.
